Yes I have experienced writer’s block more than once. I think this is something that every writer goes through at some point in their career. When it happens I usually just take a break from my writing project/s and have some fun, or focus on something else.
Don’t push yourself too hard. When writing becomes emotionally draining and stressful for you that’s the time to pause, take a break and relax. Writing just a few minutes each day can help too instead of spending hours trying to write everything in one day.
